With just $4 per resident, Jacksonville allots the lowest amount of funding for park-related expenditures. (San Antonio spends more than $52 per resident, while the American College of Sports Medicine recommends $101.)

Indianapolis is better known as a capital of racing speedsters than pedestrians; the city's Walk Score is one of the lowest at 29. (San Antonio is 34, and Austin isn't much better at 35. On the other scale, New York City steps in at 88.)

A number of factors lead to S.A.'s consistently high placement in unhealthy rankings like these. For example, San Antonians only eat half their recommended vegetables. On top of that, only about 1 in 5 people exercise more than two hours per week.

A heavy list of factors lead Memphis to be the unhealthiest city in the nation, but two are particularly alarming. Memphis has the highest rate of death from diabetes and the highest rate of death from cardiovascular disease.

While San Antonio tops a lot of best-city lists we like to tout, a recent report reiterates a less than flattering rank. BetterDoctor ranked San Antonio as one of the unhealthiest cities in the nation, and the unhealthiest one in Texas. While Austin comes in at the 18th most healthy city, Dallas and Houston join S.A. as the unhealthy dunces.

The data wizards at BetterDoctor figured in the factors like health insurance coverage, the number of doctors, and the number of highly rated doctors, with cities' American Fitness Index Score. This index score is assessed by the American College of Sports Medicine and accounts for an array of individuals' personal health indicators, like smoking and exercise, combined with environmental indicators in the community, such as parks, golf courses and public transportation.

The gallery above provides a snapshot of the unhealthiest cities in America and the factors that lead to their place on the scale. Take a look at how San Antonio stacks up; on the bright side, we're not Number 1 on this list.
